Theplate is.v then forced upward carrying the outer face offeachzplate portion 4 vand 5f into lsliding contact with the inner face ofthe short 'i f. arm of the,hookecljheadi)so'as` to slide upward thereagai'nst.intofthev position shown inFigsB.

Simultaneously withthis movement the ribs I 9 of 4,35 themechanism's 6 "and lxare held by the'plate portions 4 and-5 to travelxparallelwith'the ver.- tical facesof the hooked heads 9 toiiorce the ine ,clined plates inwardly against the .pressure ,(Jlftllel slide pieces andm'arker plate from downward In order lto prevent Vthe plates 2l andy (slide 'pieces I'I becoming detached when in the unlocked position, I provide the plate 2| with up'-v ywardly curved side tongues 24 which enter the grooves I3 and extend longitudinally thereof and the slide piece I'I with laterally extending pro! jections 25 which enter the grooves I 3. The lower end ofeach vside wall II .is provided with down--` ward extensions 26 which normally assume the position indicatedby dottedlines in Fig-5.

Whilethe projections are in this position the 55 The main `portion 'ofthe slide piece is, inthe..`

2. plateZl and slide piece l1 are inserted. The ends of the projections 26 are then turned inward as indicated at 21 into the path of the projections 25 thereby effectually locking the slide piece from withdrawal.

In order to prevent the lower portion of the `marker plate vibrating I curve the lower end of each bar 8 towards the plate and secure-the plate thereto by means of bolts 21.

In order to remove the marker plate such plate would have to be destroyed by severing the po1'. tions 4 and 5 at the outer ends of the slots Zand 3 and then bending the centre portion of theplate to make it bulge laterally soas to shortenthe distance between the aforesaid severed ends,

1 which ends would then be pulled laterally out of the hooked portions of the bars, thus removing and at the same time spoiling the marker plate forA further use. What I claim as my invention is: v

1. A' marker lock comprising a vertical bar member having a hooked upper end 'into which the upper edge of a slotted marker plate is insertable, a'slidable marker plate locking member movable longitudinally of the aforesaid bar member fromv a lower position extending below the hook to an upper position substantially within the hook and lextending outwardly therefrom to engage the slot ofA the insertable marker plate, and means coact- -ing with `that portion of the inserted marker plate which extends above the slot`thereof forautomatically securing theslidable member in the upper position.

2; In a marker lock, the combination with a marker platev having a slot adjacent its upper edge, of a bar member extending at the back of Athe plate and having a hooked upper end into which the slotted upper edge of the plate extends, locking means interposed between the plate-and the back arm of the hook and engaging the slot and adapted to beheld in the lockng'positon by that portion of the marker plate extending above the slot when interposed betweenl the' locking mechanism and the front arm ,of the hook.

3. A marker lock comprising; a verticaly bar member having a hooked upper end into which the upper edge of a 4slotted marker plate is insert'able, marker plate locking means interposed 'between the back -arm of the hook andthe inserted marker `.plate and adapted vto extend through the marker plate slotV and to be held in llocking `position by that portion. of the marker lplate extending above the aforesaid slot when interposed between locking `mechanism and the front arm of the hook, and means for preventing 4detachment-of the locking mechanism from the barA when in the unlocked position.

4. In a marker lock, the combination with a slotted marker plate, of a vertical bar member havinga hooked upper end, a slide Ipiece engaging edge, of a bar member extending at the back of the marker plate and having a hooked upper end into which the slotted upper edge of the plate extends, awall at each side of the hooked member and formed integral therewith, a slide piece slidablybearing upon the inner face of the bar and having a projection engaging the slot of the marker plate, means engaging the upper end of the slide piece when slid upward for locking the slide piece from return movement, projections extending laterally from the slide piece and coacting stops carried by the side walls limiting the downward movement of the slide vpiece when released by the removal of the marker plate.

6. In afmarker lock, the combination with the marker plate having a slot adjacent its upper edge, of a bar member extending at the back of the markerplate and having a hooked upper end into which the slotted upper edge of the marker plate extends, a wall at each side of the hooked lmember and formed integral therewith, a groove in the inner face of each wall, a spring pressed plate pivotally mounted between the side walls and-extending laterally into the grooves of the walls, such lateral edge portions forming tongues curved up from the spring plate, and a slide piece engaging the slot of the marker plate and adapted lto be forced upward together with the marker plate into the aforesaid hook poition, and means at theupper end of the slide piece engaged by the'upper edge of the-spring plate when the slide piece is forced upwardas aforesaid to lock the slide piece and marker plate within the hooked portion of the bar member.

'7. Inv a vmarker lock, the combination with the marker plate having a slotadjacent its upper edge, of a bar member extending at the back of the marker Yplate and having a hooker upper end -into which the slotted upper edge of the marker plate extends, a wall at each side of the hooked member, a groove in the inner face of each Wall, a slide plate engaging the slot of the marker plate and slidably engaging the grooves of the side w'allsandradapted to be forced upward together with the marker plate into the aforesaid hooked end, and means for automatically `locking the slide from withdrawal from the hooked endas the marker plateand slide piece are carried upward into the hook.
